MAX11167ETC+T

Analog To Digital Converters (ADC) Overview

The MAX11167ETC+T is a 16-bit, 250ksps successive approximation register (SAR) analog-to-digital converter featuring a true bipolar ±5V input range and an internal reference. It operates from a single 5V analog supply (4.75V to 5.25V) and a separate digital supply (2.3V to 5.25V). The device achieves 93.2dB SNR and -102.5dB THD with no missing codes. It utilizes a patented charge-pump architecture for direct sampling of high-impedance sources and communicates via an SPI-compatible serial interface. The component is housed in a 12-pin, 3mm x 3mm TDFN package and is specified over the -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Patented charge-pump architecture enables direct sampling of high-impedance sources without external buffering.
• Integrated internal reference with buffer reduces system cost and board space requirements.
• True bipolar ±5V input range allows measurement of 10V peak-to-peak signals on a single 5V supply.
• SPI/QSPI/MICROWIRE/DSP-compatible serial interface supports daisy-chaining for multichannel applications.

Analog To Digital Converters (ADC) Applications

• Data Acquisition Systems
• Industrial Control Systems/Process Control
• Medical Instrumentation
• Automatic Test Equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ETC' against the manufacturer's official ordering guide to confirm tape-and-reel packaging and lead-free status. Ensure the source impedance of the driving circuit does not exceed recommended limits to maintain 16-bit accuracy during the acquisition phase. Confirm that the digital supply voltage aligns with the host controller logic levels before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-supply solution is required for bipolar signal acquisition at 16-bit resolution. The internal reference simplifies design by eliminating external precision references. Consider the 250ksps throughput rate and 3mm x 3mm package size for space-constrained industrial or medical designs requiring high DC and AC accuracy.

Analog To Digital Converters (ADC) Part Context

The MAX11167 belongs to the Maxim Integrated 14-Bit to 18-Bit SAR ADC family. It shares architectural similarities with the MAX11166, MAX11168, and MAX11169, which offer varying resolutions and speeds within the same ±5V input category. This specific model targets applications needing 16-bit performance at 250ksps with integrated reference capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's current product selector guide for potential obsolescence management or pin-compatible alternatives within the MAX111xx series.
